Description

Technical Field

[0001] The invention relates to the technical field of dock collision test equipment, in particular to a dock ship collision simulation test box capable of avoiding simultaneous vibration. Background Art

[0002] In the dock ship collision simulation test, water is generally added inside the simulation box, and the simulated ship moves inside the simulation box and collides with the baffle of the dock model for the test. This working method is disclosed in the public document of a dock ship collision simulation test box with application number CN201920348543.0. However, when the simulated ship collides with the dock model, because the dock model is fixedly installed inside the simulation box, when the simulated ship collides with the dock model, the expansion force will directly act on the simulation box, causing the simulation box to vibrate along with the dock model, which is likely to cause the equipment for detecting the test data to jitter and affect the test results. In addition, the test is carried out inside the simulation box, and the size of the simulation box is certain. Therefore, after the simulation box is vibrated, it is easy to cause the water inside the simulation box to vibrate, causing the water to fluctuate unexpectedly, which is likely to affect the test results. For this reason, we propose a dock ship collision simulation test box that can avoid simultaneous vibration. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Embodiment 1:

[0022] The present invention provides a technical solution: a dock ship collision simulation test box that can avoid simultaneous vibration, please refer to Figure 1 , including a simulation box 1;

[0023] See also Figure 1 and Figure 2 , a mounting plate 2 is fixedly installed on the inner wall on the right side of the simulation box 1, and a detection device 4 is fixedly installed on the outer wall on the top of the mounting plate 2. The detection device 4 refers to equipment such as a camera, a laser rangefinder, and a sensor, which is used to detect the force and movement amplitude of the simulation baffle 31 of the simulation device 3, which is consistent with the detection equipment in the public document of a dock ship collision simulation test box with application number CN201920348543.0, and the working method is consistent. Water will be added to the simulation box 1, and the wave maker will work to generate water waves inside the simulation box 1 to simulate the situation at sea in the area where the dock is located. The model ship moves on the water and expands the simulation baffle 31 of the simulation device 3, and the state of the simulation baffle 31 is detected to simulate the situation of a dock ship collision. The simulation device 3 is movably installed at the bottom of the inner cavity of the simulation box 1, and a wave maker is installed on the inner wall on the left side of the simulation box 1. The electrical equipment involved in the device is electrically connected to the external power switch through wires;

[0024] See also Figure 2 and Figure 3 The simulation device 3 includes a mounting seat 32 fixedly connected to the bottom inner wall of the simulation box 1, a slide groove 34 is opened on the top outer wall of the mounting seat 32, a slider 33 is slidably installed in the inner cavity of the slide groove 34, a support spring 35 is installed between the right outer wall of the slider 33 and the inner cavity of the slide groove 34, and the top of the slider 33 extends to the top outer wall of the mounting seat 32 and is fixedly connected to the simulation baffle 31. When the simulated ship collides with the simulated baffle 31, the simulated baffle 31 is subjected to force, which will compress the support spring 35, so that the slider 33 slides to the right in the inner cavity of the slide groove 34, and the simulated baffle 31 slides to the right on the mounting seat 32, so that the force generated by the collision of the simulated baffle 31 will not directly act on the simulation box 1, so that the simulation box 1 will not vibrate due to the collision of the simulated baffle 31, thereby avoiding the deviation of the detection device 4 and avoiding large fluctuations in the water inside the simulation box 1, thereby ensuring the accuracy of the detection;

[0025] See also Figure 2 and Figure 3 Baffles 36 are fixedly installed on the top outer walls on both sides of the slider 33, and openings are opened on the top inner walls on both sides of the slide groove 34. The end of the baffle 36 away from the slider 33 passes through the opening, and the outer wall of the baffle 36 fits with the inner wall of the opening. The baffle 36 blocks the slide groove 34, so that water in the simulation box 1 will not enter the interior of the slide groove 34, thereby preventing water from entering and affecting the sliding of the slider 33 in the inner cavity of the slide groove 34, thereby ensuring the accuracy of the test.

[0026] Embodiment 2:

[0027] See also Figure 2 and Figure 3 On the basis of Example 1, a support block 37 is slidably installed on the right side of the inner cavity of the slide groove 34, and the left outer wall of the support block 37 is fixedly connected to the right end of the support spring 35. A threaded hole is opened on the right inner wall of the slide groove 34, and a threaded sleeve 39 is screwed on the inner cavity of the threaded hole. A moving rod 38 is arranged on the left outer wall of the threaded sleeve 39, and the left end of the moving rod 38 is fixedly connected to the right outer wall of the support block 37. The threaded sleeve 39 is rotated to make the moving rod 38 move rightward with the support block 37, so that the compression degree of the support spring 35 changes, so that the supporting force of the support spring 35 on the slider 33 becomes larger, and the difficulty of the simulation baffle 31 moving to the right can be changed, so that the supporting force of the support spring 35 can be changed according to the collision force between the ship and the simulation baffle 31, so that the right side of the slider 33 will not contact the right inner wall of the slide groove 34, so as to avoid the vibration force caused by the collision of the simulation baffle 31 to the simulation box 1 due to the contact, and further avoid the vibration of the simulation box 1 due to the test;

[0028] See also Figure 3 and Figure 4 The threaded sleeve 39 includes a rotating sleeve 392 inserted in the inner cavity of the threaded hole, the outer wall of the rotating sleeve 392 is provided with an external thread matching the threaded hole, the left side of the inner cavity of the rotating sleeve 392 is rotatably plugged with a mounting sleeve 391, the right end of the moving rod 38 is slidably plugged in the inner cavity of the mounting sleeve 391, and a threaded rod 393 is fixedly installed on the right inner wall of the rotating sleeve 392. The inner cavity of the mounting sleeve 391 is filled with air. When the slider 33 moves to the right, the support spring 35 is compressed, and as the slider 33 moves to the right, the degree of compression of the support spring 35 will also increase. When the distance between the slider 33 and the support block 37 is small, the support spring 35 is compressed to a large extent, which will make the tension of the support spring 35 greater than the air pressure inside the mounting sleeve 391, which will push the moving rod 38 to the right, so that the support The block 37 moves to the right to increase the spacing between the support block 37 and the slider 33, ensuring that there is no collision between the slider 33 and the support block 37, so that the simulation box 1 does not vibrate. A piston plate 394 is slidably installed on the right side of the inner cavity of the mounting sleeve 391. The left end of the threaded rod 393 penetrates the piston plate 394. A screw hole is provided at the connection between the piston plate 394 and the threaded rod 393. When the threaded sleeve 39 rotates to increase the compression degree of the support spring 35, the threaded rod 393 will also rotate to move the piston plate 394 to the left, thereby increasing the air pressure between the moving rod 38 and the piston plate 394. When the compression degree of the support spring 35 increases, the air pressure inside the mounting sleeve 391 increases, so that the moving rod 38 will not move to the right due to the increase in the tension of the support spring 35, thereby avoiding the deterioration of the adjustment effect of the support spring 35.

[0029] Compared with Example 1, components such as a support block 37, a threaded sleeve 39 and a moving rod 38 are added. By rotating the threaded sleeve 39, the supporting force of the support spring 35 is changed, so that the difficulty of moving the simulated baffle 31 to the right can be changed. Therefore, the supporting force of the support spring 35 can be changed according to the collision force between the ship and the simulated baffle 31, so that the right side of the slider 33 will not contact the right inner wall of the slide groove 34, thereby avoiding the vibration force generated by the collision of the simulated baffle 31 on the simulated box 1 due to the contact.

[0030] Embodiment 3:

[0031] See also Figure 2 , Figure 3 and Figure 5 On the basis of Example 1, through holes 310 are evenly opened on the left outer wall of the simulated baffle 31, through which water can pass through the simulated baffle 31, so that when the simulated baffle 31 moves to the right after collision, the blocking force of water on the simulated baffle 31 becomes smaller, and a guide block 312 is arranged on the right top outer wall of the simulated baffle 31, and a guide groove 311 is arranged on the left outer wall of the mounting plate 2, and the right end of the guide block 312 is slidably inserted into the inner cavity of the guide groove 311 to guide the movement of the simulated baffle 31 and support the simulated baffle 31, and an insert block 314 is fixedly installed on the left outer wall of the guide block 312, and a slot 313 is arranged on the right outer wall of the top of the simulated baffle 31, and the insert block 314 is inserted in the inner cavity of the slot 313, and the insert block 314 can be moved out of the inner cavity of the slot 313 upward, and openings 315 are arranged on the inner walls on both sides of the guide groove 311, and water will enter the inner cavity of the guide groove 311 through the opening 315, The guide block 312 plays a supporting role, thereby supporting the simulated baffle 31, so that the probability of the simulated baffle 31 being skewed due to collision is reduced, and a guide rod 316 is slidably installed in the inner cavity of the opening 315, and a connecting spring 318 is sleeved on the outer wall of the guide rod 316, and one end of the connecting spring 318 is fixedly connected to the outer wall of the guide rod 316, and the other end of the connecting spring 318 is fixedly connected to the inner wall of the opening 315, and the ends of the two groups of guide rods 316 away from each other are fixedly installed with a stopper 317, and the stopper 317 is located in the inner cavity of the opening 315, and the diameter of the vertical section of the stopper 317 is smaller than the diameter of the vertical section of the opening 315. When the guide block 312 moves to the right in the inner cavity of the guide groove 311, when the water pressure inside the guide groove 311 increases, the stopper 317 will be pushed outward, so that the opening 315 is opened wider, so that water can flow out more quickly, avoiding affecting the rightward movement of the simulated baffle 31.

[0032] Compared with Example 1, components such as a guide block 312 and a guide groove 311 are added. Water enters the inner cavity of the guide groove 311 through the opening 315, and has a supporting effect on the guide block 312, thereby supporting the simulated baffle 31, thereby reducing the probability of the simulated baffle 31 being skewed due to collision.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
